I am five weeks out from my second TKR. While I am ahead of my therapy goals compared to my first TKR, (in July), I am also plagued by sleep issues. (Should mention that I have Sleep Apnea. Normally it is well managed with my Bi-Pap).
Even now, I can go to bed following an active day, ready for sleep, but awaken within an hour or two. Initially I would awake with fairly significant pain, now it is more discomfort, an inability to find a comfortable position. Even when I do find sleep it is often restless, a lot of turning and tossing. I use my device, we have blackout curtains in the bedroom and lower the thermostat at bedtime.
My journal reminds me that it was nearly six weeks after the first surgery before sleep became normal again. My surgeon tells me disrupted sleep is the second most common complaint post-surgery. (The first is, of course, pain).
It is unfortunate, given that the surgery and rehab is difficult enough, to have to endure poor sleep for several weeks afterwards. Hopefully people considering TKR are advised of this upfront.
